IMPROVEMENT IN WIND-WHEELS.

The Schedule referred to in these Letters Patent and making part of the same.

- To whom it may concern Be it known that I, LUMAN M. GODFREY, of Colon, in the county of St. Joseph, and State of Michigan, have invented a new and useful Improvement in Wilidmills; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawings, alid to the letters of reference marked thereon, and beilig a part.- of this specification.

The nature of this invention relates to an improved and siinpltiedconstruction of a wilidmill, by means of which the power lilay be indefinitely multiplied, by the lengthening of the shaft, alid the addition of all indefinite number of arms and sails, or wings.

4 'lhe invention consists ill a proper bearing, rigidly secilred to a sllitable shaft.

\Vithin this bearing is sleeved an arm, at its centre, each end of which is provided with a sail, so al'- ranged relatively to and with each other that they are attached to the armat right angles.

By this arrangement, when the iliill is stationary for want ot' wind, the sailsiueline downward, at an angle of about forty-live degrees.

Vhen the-wind commences to act upon the mill, itacts directly upon bot-h the sails, compelling the one t0 assume a vertical posit-ion, against which vthe wilid will act with great force, td propel the apparatus, while at the saliie time the wind will act upon `the opposite sail, and compel it to assullie a horizontal posit-ion, thereby presenting its edge only to the wind, and oiering the least possible resistance to its passage.

As soon, 'in its rotation` as the sailpasses out of the line of direction 'of the wind, by its own gravit-y, it *will assume the position first described, wlienthe next sail ili vthe series will be similarly acted npoli, thereby obtainng'a const-ant direct power upon the apparatus. v

'llie advantages '1 claim over other devices for a similar purpose, are- First, its ofl'eat simplicity, there heilig no mechanism reqnired to throwa sail edgewise to the wind, after it has done its work, and rotated'out of lille of thel winds passage. This inotioll is automatic, and the sails self-adjusting in my apparatus.

Second, its economy in construction, saving, as it does, liiore than three-quarters the expense attending the construction of the windmills in ordinary use. l

Third, the ready and easy method of increasing the power, by simply adding to the shaft more arms and sails. As these are arranged one above the `other lipolrthe shaft, so that they act freely alid independently of each other, an indefinite number inay be added, until the power required is obtained.

Fourth, the fact that my apparatus will be equally as valuable, alid work equally well with the shaft in a horizontal as in a vertical position, and will make oneof the. best current-wheels for use ill water.

In the drawings- A represents a vertical shaft, properly joulnalled aiid secure-ll, so that it will freely rotate, alid to which is secured suitable gearing, to communicate its power to the object to be driven.

B are hollow bearings, rigidly secured to and at right angles with the shaft A.

O are roliiid arms, sleeved within the bearings B, with ends projecting beyond the saine at either end, to which are secured the sails or wings D, which are fastened to said arms, so as to be at right angles with each other.

lli the drawings, the lower arm has its sails presented so that the one is heilig acted upoli by the wind, while the other is thrown up edgewise to the wind.

llie ariii next above on the shaft, shows one sail just being broilghtilito action, while the otheris being thrown np edgewise.

llie upper arln' has its sailsinv the position herein iil'st described.

Ally suitable mechanism may be employed to hold the apparatus stationary wlieil desired, or the colinectilig-machinery n'lay be thrown `out of gear, and the iiiill be allowed to run with less strain upon the shaft,

\Vllat .I claiiii as my invention, and desire to secure l Witnesses:
